[SOLVED] Dell PowerVault ME5012 Don't show LUNs

Hello everyone, I'm trying to add an iscsi disk, it adds without problems in the portal, but when I go to add the LVM, it doesn't appear.
The Storage used is the Dell PowerVault ME5012 model.
Observation 01: On windows it works perfectly.
Observation 02: When TrueNAS was being used it worked perfectly too.

ISCSI(I deleted the IP and part of the target from image):

LVM(I deleted the node name from image):

I resolved it by running the command below, to disconnect all iSCSI sessions on all nodes.

iscsiadm --mode node --targetname "iqn...." --portal "<ip_server>:3260" --logout

I installed the multipath-tools package:

apt-get install multipath-tools

So I edited the /etc/multipath.conf file and added the following configuration:

##Default System Values
defaults {
user_friendly_names yes
find_multipaths yes
max_fds 8192
polling_interval 5
queue_without_daemon no
}

## Blacklist Exceptions
blacklist_exceptions {
device {
vendor "DellEMC"
product "ME5"
}

}
## Dell Device Configuration
devices {
device {
vendor "DellEMC"
product "ME5"
path_grouping_policy group_by_prio
path_checker "tur"
hardware_handler "1 alua"
prio "alua"
failback immediate
rr_weight "uniform"
path_selector "service-time 0"
}
}

in the terminal, I used the command below, to restart the service:

systemctl restart multipath-tools.service

After that, I went back to WEBGUI and the LUNs appeared.
